Product Description

Teacher Directions
Have students work in groups of 3 – 4, each person is playing by themselves against their group members.
Materials needed for each group:
• 1 f(x) function die
• 1 g(x) function die
• 1 six-sided die
*Tip: print the function die cubes in different colors so it is easier for the students to keep track of the difference between the two dice.
Directions for students:
1) Roll all 3 dice
2) In rounds 1 – 6: Complete the problem (f + g)(x) on a separate piece of paper
a. Fill the x in with the number you roll on the six sided die
b. Example: If I rolled f(x) = 5x – 10, g(x) = 6x + 2, and a 4 on the six sided die, I would solve (f + g)(4) = 5(4) – 10 = 20 – 10 = 10 and 6(4) + 2 = 24 + 2 = 26, so 10 + 26 = 36
3) In rounds 7 – 12: Complete the problem (f – g)(x) on a separate piece of paper
a. Fill the x in with the number you roll on the six-sided die
b. Example: If I rolled f(x) = 5x – 10, g(x) = 6x + 2, and a 4 on the six sided die, I would solve (f - g)(4) = 5(4) – 10 = 20 – 10 = 10 and 6(4) + 2 = 24 + 2 = 26, so 10 – 26 = -16
4) Keep a running total of your score, the person with the highest score wins

Adjustments:
• You can adjust the number of rounds based on the amount of time you have for the activity. All students can be working on their own problem at the same time. Each round took my students about 2 – 4 minutes.
• You can also do this a whole class activity.
• Can use other composite functions with dice
